about_PSVersionCompare SHORT DESCRIPTION The PSVersionCompare module contains functionality for comparing commands between Windows PowerShell versions. By running Compare-PSVersionCommand and specifying either a set of 2 computer names or 2 XML-files to run the comparison against, output will be returned indicating whether a command or parameter is added (+), changed (!) or removed (-). LONG DESCRIPTION Due to the new and fast moving pace Microsoft have gotten into, we will see more frequent updates to PowerShell than before. Version number is one element, another one which is not easy to keep track of as a regular PowerShell user is what commands are new or changed. For example, parameters might be added or removed from existing cmdlets. At the time of this writing, a new technical preview of Windows Server 2016 has just been released. But how can you know what is changed with regards to PowerShell commands? Since the need to perform this task will occur more and more often going forward, the PSVersionCompare module was created with a reusable function. The function is named Compare-PSVersionCommand. You can either get it directly from GitHub, or use PowerShellGet to install it from the PowerShell Gallery: Install-Module -Name PSVersionCompare In the initial version, Compare-PSVersionCommand have two parameter sets which makes it possible to compare based on either XML-files pre-gathered from systems, or data gathered directly via PowerShell remoting.
